Abstract |
A mathematical model of a multipurpose reservoir is formulated taking into account such factors as: flow augmentation, the stochastic nature of inputs, requirements on the reservoir level, and the hydroelectric function of the reservoir. Based on the model an optimal solution to the problem of allocation of the impounded water is determined. These optimal polices or strategies are determined by (probabilistic) dynamic programming for which the objective is to minimize the expected total discounted cost over a finite horizon. These general results are in the form of theorems, some of which are represented graphically. A numerical example, to illustrate the results, and general implementation remarks are included.
